Hello everyone,


I'm having some problems with printing Nexeo/DSM Novamid ID 1070 on an Ultimaker S5. 

I'm experiencing some warping and bed adhesion issues. My parts warp in the corners and I also see that they partially come loose from the build plate.. 

I also enlarged the brim a little bit, I might need to make the brim even bigger.

I'm using 3DLac as an adhesive promotor.


I'm using printer settings provided by the supplier (I'll post them below). 


I have a document from Nexeo where they give some advice when you are experiencing problems. Unfortunately this a little bit contradictory..


This is what they say:

Warping: Advice is to lower the build plate temperature.. etc. 


First layer not sticking/parts coming loose: (amongst other tips) Advice is to raise bed temperature.. 


This are some of the print settings I use:

Print temperature: 255 °C

Bed temperature: 60 °C

Layer height: 0,2 mm


Should I raise or lower my bed temperature? And are there other tips to make sure my parts come out fine?


Thanks in advance!

    I've printed Novamid 1030 but not 1070.  But I've printed probably 7 different types of nylon filament and they are mostly the same.  However 1070 is much stiffer than most filaments so it will be much more difficult where "warping on corners" is concerned.


    First of all 60C is crazy.  Stupid.  Bad.  100C will be much better.  The recommended temp I found on the internet for Novamid 1070 is 100C to 120C.  Nylon is very different from PLA in a few ways - first of all it gets softer very gradually as it gets warmer so at 80C it will be more flexible than at 60C and at 120C it will be getting very flexible but it will always bend back.  In comparison, PLA gets like clay as it gets warmer - if you deflect it when it is above 52C it will stick with it's new position.  LIke if you poke clay.  But Nylon when it's at these temps will bounce back.  Like rubber.


    Anyway make sure you set the bed to 100C.  I recommend cutting a 10cm length, bend it a few times in your hand and remember what it feels like, then place it on the bed at 100C for 20 seconds, then pick it up and bend it again.  Sometimes touching your filaments at temps of 60C, 80C and 100C (and 110C for ABS) can be enlightening.  Try bending it enough so it will permanently in a new shape.  I don't think that will happen at temps below 110C for Nylon.


    It's important to use lots of brim in cura.


    When I print Nylon I coat the glass with a very thin layer of PVA.  You should use some kind of surface treatment like 3DLAC or hairspray or woodglue mixed with water or gluestick spread on the glass with a wet tissue (to remove 90% of it and to spread it extra thin).  Don't just use gluestick by itself without spreading it super thin. However, one time when I printed UM Nylon with that thin layer of gluestick it stuck too well and removed a sliver of glass from my S5 print bed.  UM recommends a thick layer of gluestick to protect the glass.  So maybe start with that and if it's still warping then do a thin layer of gluestick.  I have a video that shows how I do PVA - 3 different methods.  If you use my methods parts will stick so well you will be chipping the glass occasionally.  It's worth it. My glass budget is tiny compared to my filament budget.

    One more thing.  Nylon absorbs water from the air like crazy.  If you have left your filament out in the air for a day or two you need to dry it.  Set the print bed to 90C and put the whole spool of filament on the bed and cover it with a towel (or put the filament in a closed cardboard box - towel is better).  Or cover with a sheet.  Leave overnight like this.  If you are only printing 1 meter of nylon then you can cut 2 meters (one for the bowden) and leave that on the bowden at 100C for 20 minutes.


    I keep my nylon stored with a large (fist sized) box of rechargable dessicant (very cheap on ebay) that changes color when the dessicant needs to be recharged in the microwave.


    If you don't keep the nylon dry it doesn't stick as well to the glass and it foams as the water inside boils.  If it's very wet you can hear the sizzling and popping as the nylon comes out and you can see steam.  And the nylon isn't clear - it's like snow (matte).  Instead of like ice (clear, glossy).


    But if it's only a little wet you can't see a problem but it doesn't print as well.

    Hello @gr5,


    Thank you very much for your reaction! I will definitely change the bed temp to 100 degrees celcius and try it again!


    Also, I try to keep the filament spool as dry as possible. We also have a filament dryer, so before I start printing again I will put it in the dryer for a few hours!

      • Here it is. The new UltiMaker S7
        The UltiMaker S7 is built on the success of the UltiMaker S5 and its design decisions were heavily based on feedback from customers.
        So what’s new?
        The obvious change is the S7’s height. It now includes an integrated Air Manager. This filters the exhaust air of every print and also improves build temperature stability. To further enclose the build chamber the S7 only has one magnetically latched door.
        The build stack has also been completely redesigned. A PEI-coated flexible steel build plate makes a big difference to productivity. Not only do you not need tools to pop a printed part off. But we also don’t recommend using or adhesion structures for UltiMaker materials (except PC, because...it’s PC). Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly – even with one hand.
        The re-engineered print head has an inductive sensor which reduces noise when probing the build plate. This effectively makes it much harder to not achieve a perfect first layer, improving overall print success. We also reversed the front fan direction (fewer plastic hairs, less maintenance), made the print core door magnets stronger, and add a sensor that helps avoid flooding.

        The UltiMaker S7 also includes quality of life improvements:
        Reliable bed tilt compensation (no more thumbscrews) 2.4 and 5 GHz Wi-Fi A 1080p camera (mounted higher for a better view) Compatibility with 280+ Marketplace materials Compatibility with S5 project files (no reslicing needed) And a whole lot more  
        Curious to see the S7 in action?
        We’re hosting a free tech demo on February 7.
        It will be live and you can ask any questions to our CTO, Miguel Calvo.

      • UltiMaker Cura 5.3.0-Alpha 🎄 Tree Support Spotlight 🎄
        Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
        We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.
